"Anyone who has heard the words of Erdogan, which were full of hate and incitement, recognizes no doubt that we are dealing with a successor of [Nazi Minister of Propaganda Joseph] Goebbels," said Lieberman. "His conspiracy theories are of the same nature as the Dreyfus Affair and the hateful blood-libel 'The Elders of Zion.'"

In a party conference speech earlier in the week, Erdogan said that his government could prove that Israel is behind the unrest in Egypt. As evidence, he cited the words of Jewish intellectual Bernard-Henri Levy in a 2011 conversation with the then-Israeli opposition leader Tzipi Livni. Levy said at the time: "The Muslim Brotherhood will not remain in power, even if they win the elections, because democracy is not the ballot box."

In commenting on Levy's words, Erdogan stated: "Now, the West says that democracy is not the ballot box, or not only, but we know that the ballot box is the will of the people. And this was implemented in Egypt. Who's behind this? Israel. We have evidence."

Lieberman is known for his rough and outspoken demeanor, and often compares Muslim politicians who want to destroy Israel to the Nazis. But with Erdogan, he might not be so far off the mark.

The Turkish leader is equally infamous for his conspiracy theories, which he disseminates with abandon any time the situation is not going according to plan. During Turkey's own recent pro-democracy demonstrations, Erdogan attributed the near-uprising to a conspiracy against him contrived by "world Jewry."
